My invention relates to a new and useful combined safety guard and anti-sind device which is particularly adapted for appllcation to the wheels oi self-propelled vehicles such as automobiles, trucks and the like, whereby the dan er of overturning due to a blow-out when t e motor car is traveling at a high speed and whereby the motor car 1s guarded against slipping1 and skidding.

My invention still rt er relates to a combined safety guard and anti-skid device which is carried by the wheels of the vehicle permanently, the safety guard bein adapted to be automatic in its operation, t at 1s, to be available for emergency at any time, and the anti-skid device being adapted be applied for use in a minimum of tune and aber. l

My invention still further relates to a novel device of the general character stated, which may be incorporated or built-in in wheels when the same are being manufactured, or which may be applied to wheels of vehicles already in actual use.

My invention still further relates to a device ot the general character stated which is l extremely sim le in construction, economiweather or on muddy roads.

cal in cost an attractive in appearance so that the appearance of the vehicle to the wheels of which my novel device is applied is improved.

It has been the practice heretofore to employ anti-skid chains which are normally carried in the tonneau of the vehicle or under the rear seat to be applied to the wheels when the slippery character of the road necessitates the use of said chains. Chains of this character can not be applied without first raising the wheels o" the road and locking said chains in osition. This is a .task oi tremendous di culty especially in cold Furthermore, it often ha pens that astretch of road .is slippery and the rest is dry, and vice versa, and due to the diiiiculty of applying and removing the chains, the motorist 1s apt to dispense with their use or to fail to remove them, increasing the hazard in one case and increasiner the wear and tear The expeients heretofore adopted to remedy on the left hand in the other.

this condition have consisted generally in providing spikes that are adapted to engage the roadA when a blow out occurs and in providing chains carried by the Wheels and adapted to be spread around the tread of the tire, the latter structure, however, while aiming at the same objective as the present invention, differ materially in the structure and assembly hereinafter shown `and described.

'llo the above ends my invention consists of inner and outer rigidly carried rims of a sli htly smaller diameter than the diameter in ated tire, said rims bein provided with annular bands of solid ru loer and being adapted to enga e vehicle when ai tire is deated.

My invention further consists of a series of chains of a length sucient to extend low out occurs or when a across the tread of an inflated tire, said chains being carried by the inner sides of the wheels in an inoperative position to be applied to the operative position at will, without the necessity of raising the wheels from the road.

My invention still further consists of springs which are adapted to hold said chains in taut manner to prevent rattling when not in use and to maintain said springs in position when in use.

My invention still further consists in various other novel features of construction and advantage all as hereinafter described and claimed in connection with the accompanying drawings, in which:

Referring to the drawings, in which like reference characters indicate like parts, and with particular reference to Figs. 1 and 2, I have shown a novel wheel construction embodying my invention vwhich comprises an outer rim 12 and an inner rim 13, each of said rims being split as at 11 andjoined by the. plate or link 11X and being provided at their peripheries with the annular seats or -grooves 14 which receive and engage the rubber bands 15. The outer rim 12 is provided with the integral seat 17 which receives the iniiated tires 18 and with the iiange 19 which is provided with the aperture 20. 22 indicates an apertured lug provided adjacent the outer end of seat 17, and will herein after be further referred to. rEhe inner rim 13 is provided with integral body portion 24 which has the aperture 26 and which aligns with the aperture 20 in the iange 19 of the outer rim 12, for receiving the bolt or other fastening means 28 for holding the inner and outer rims together to form a wheel. Anchored to a suitable point 30 in the body of the inner rim 13 is a spring 31 which is connected at the front or Jfree end thereof with the inner end of the anti-skid chain 32, said anti-skid chain being adapted to pass through an opening 39 in the body of the inner rim 13, and being provided with a hook 34 adapted to engage the apertured lug 22 in a manner hereinafter set forth.

In Figs. 6 and 7 I have shown my invention asapplied to a conventional wooden wheel of an automobile, wherein I use an inner split rim 40 provided with the annular seat 14 holding the annular band 15, and having the opening 33 for the passage oi' the chain 32. 41 designates a split band cla-mped around the inner hub of the wheel and having the apertured lug 42 to which may -be anchored the inner ends of the springs 31 which carry at their other ends the anti-skid chains 32 in the manner heretofore described. The rim 40 is suitably secured to the inner side of an automobile wheel by the bolts 28 which pass thru the rimof the wheel and which normally serve to hold the conventionalretaining split ring 44 in position. 45

designates an outer split rim which carries a seat 14 holding a band o r tire 15 and the apertured lugs 22 for engaging the hooks 34 at the free ends of the chains 32. The remainder of the structure illustrated in Fig. 7 is conventional and need not be further described.

In Figs. 8 and 91 have shown a further modification of the invention wherein I employ inne-r and split rims having the seats 14 and bands 15 and being secured together by the bolts 43, the outer rim (not shown) being preferably identical with the structures shown in Fig. 4 and in the right hand portion oi' Fig. 7, and the inner -iini being provided with the inwardly projecting arms 48 which carry the hooks 49 for engaging the inner ends of the springs 31, thel yhooks '49 on the inner ends of lthe arms 48 being in the bottom or outer surface thereof serrated as at 51, said blocks being flexibly connected by the links 52 which ,are engaged by the pivot pins 53. g l

rlhe operation is as follows: `When1the tire 18 blows out or is deflated, the bannis 15 engage the road thereby supporting the car and preventing damage of the inner tube in the tire 18.

1i, however, a blow out occurs at high speed, the vehicle is, if not provided with the bands 15, in grave danger oi' overturning due to the sudden stopping which results from the engagement ot' the iron rim of the wheels with the road. Vith the rubber bands V15 engaging the road in the case oi a blow out, the car will continue to run and will slowly come to stop.

The anti-skid chains, whether of the structure shown in Figs. 2 and 7 or of the structure shown in Fig. 10 are of a length .suiiicient to circumscribe or go around an inflated tire 18, and are of a thickness or diameter which permits their free passage through the openings 33, the hooks 34 at the ends of said chains being larger than and not passable through the openings 33. Thus, when it is desired to apply the anti-skid chains, it is merely necessary to pull the hooks 34 out by means of a screw driver or other elongated tool, and against theI tension of the springs 31, said hooks being then engaged by the apertured lugs 22, located at a point opposite to the openings 33. In this positio'n of the parts the springs 31 aredistended or stretched andthe chains 32 are extended entirely across the tire 18, as at A in Figs. 1, 6 and 8. (See also Figs. 2 and 7.) `When it is not desired to use the anti-skid chains 32 it is merely necessary to disengage the hooks 34 from the lugs 22, whereupon the sprin s 31 resume their contracted position as at in Figs. 1, 6 and 8 and in this position of the parts the hooks 34 which are larger than the openings 33 abut against said openingsand prevent the complete withdrawal of the chains 32, which now extend in a taut manner between the outer ends of the springs 31.

i over-all diameter adapted to pass freely By being thus drawn taut, the chains 32 are prevented from rattling or in any way interering with the rest of-the structure.

While the form Aof my invention illustrated in Fig. 2 is particularly adapted to the structure of new Wheels of the type known as disc wheels, and that shown in Fig. 7 is adapted for use on the conventional wooden Wheels I have shown-inFigs. 8 and 9 a form of the invention which enables me to equip any wheels now in use, regardless of their size, structure or nature with both the antiskid guards and the chains, without in any Way interfering with the structure and` at very little cost. The inner and outer rims employed in the various forms of the inven'- tion illustrated in the drawings are split to faciliate the application and removal of the ire 18 or annular bands 15 as the case may Claims:
